Abstract (en)
[origin: US4426963A] A light metal cylinder head for a valve-controlled internal combustion engine. The cylinder head is provided with at least one insert introduced into that bottom portion of the cylinder head located between the valves, and also has a bore, in that portion of the cylinder head bottom which faces the combustion chamber, for an injection nozzle or a straight channel and/or for an ignition aid, whereby at least the bottom region located between the valves, including the bore region, is coated with a crack-precluding oxide layer. In addition, that portion of the insert which comes into contact with the oxide layer is coated with a material which is resistant to the method of producing the oxide layer.
